In this forum I have read that a raised floor in a Core and Shell project does not need to be included in IEQc3.4 because the floor will be covered later by the tenant. Others on the other hand say that the raised floor needs to be included for IEQc3.4 Can anyone confirm if raised floors need or need not to be included?

A raised floor is considered part of the base building and is therefore not a floor finish. Anything put on top of the raised floor would need to be included in IEQc4.3.

Hai Ward,
I have the same question with Emmanuel. Thank you for your clarification, but can you give me the reference about the statement that a raised flooring structure or underlayment is not subject to the IAQc4.3 requirements.

There are several locations this can be found/surmised from discussions on other rating systems on this forum like http://www.leeduser.com/credit/ci-2009/IEQc4.3, but if you are looking for act words in black and white - good luck! You can also look at LEEDv4 (http://www.usgbc.org/node/2634658?view=guide) you will notice raised flooring is missing from the list of materials that must be compliant. This does not mean it is not desirable to use a Floorscore certified raised flooring, which can be found from the http://rfci.com/ website. All this being said does not mean a raised flooring is not covered by LEED, as it is, simply not by this credit. In most cases the raised flooring is made out of some form of composite wood, so IEQc4.4 does usually apply, as would IEQc4.1&4.2 for adhesives or coatings that may be used as a part of the raised flooring system.
